What modifications do you want to see in the old AoK and AoC campaigns?

The devs have pretty openly talked about their intent to switch around some things in the old campaigns in definitive edition that they previously haven't touched. What would you like to see changed? Here a list of things I wouldn't mind seeing:

-Up the pop cap from 75 to at least 150, I realized that one of the reasons that I like the Attila campaign so much is that its the only campaign where this shackle has been removed consistently, we don't have performance issues to worry about any more so I imagine this would be simple enough, but it may unbalance certain missions and require some buffing to the enemy.

-Have the relevant civs replace their awkward facsimiles where it makes sense, the main ones that come to my mind is the Italians in Barbarossa 3 and 4 (though maybe they could keep the Byzantines as Venice there), Slavs instead of Goths for the Poles in Barbarossa 2, Berbers as the, you know, Berbers in the Charles Martel mission and also maybe to replace Yusuf's forces in the El Cid missions, Slavs instead of Goths in Genghis Khan 4 and definitely Magyars instead of Teutons in 6.

-Maybe spruce up some of the older maps with more eye candy, Forgotten empires is pretty good at that in the stuff they make themselves and I noticed they released a screenshot for the Noryang Point mission that showed some changes in terms of things like the layout of buildings.

Of course if you prefer that things were kept more traditional I that's perfectly understandable, but I think that this could be a good opportunity for some updates myself.
